When someone critises or disagrees with you, a small ant of hatred and antagonism is born in your heart. If you do not squash that ant at once, it might grow into a snake, or even a dragon.
RumiBe like the sun for grace and mercy. Be like the night to cover others' faults. Be like running water for generosity. Be like death for rage and anger. Be like the Earth for modesty. Appear as you are. Be as you appear.
Rumi
